Bloc for Freedom and Progress

The Bloc for Freedom and Progress, also known as the Khoi Tu Do va Tien Bo (KTDTB), was a pro-democracy bloc in South Vietnam which was active from April to November 1960. It was founded by the signers of the April 1960 Caravelle petition, which demanded democratic reform under Ngo Dinh Diem's government, and the organization made little headway due to the failure of a November 1960 coup against Diem. Suu was imprisoned by the government after the coup, and other members of the group suffered harassment and remained largely ineffective.
